The National Labor Relations Board recently made it more difficult for employers to withdraw recognition of an incumbent union.
For the past 50 years, employers needed only a good-faith belief that the union no longer had the support of a majority of the workers. Under the new decision, you must now prove that the union actually has lost that support. (Levitz Furniture Co., 333 NLRB 105)
At the same time, the board made it easier for employers to get a board-conducted election to gauge the union's support, requiring only a good-faith uncertainty about the union's status.
